Substantiation

De fase 3 studie bij pediatrische patiënten met refractaire myasthenia gravis is nog niet officieel gepubliceerd. In de klinische trial (NCT03759366) worden 11 kinderen, in de leeftijd 6 tot 17, met refractaire en AChR-positieve gMG behandeld met Soliris voor 26 weken. De resultaten laten zien dat de gemiddelde score op de Quantitative MG (QMG) schaal, die de mate van MG meet, met 5,8 punten toenam. Dit toont aan dat ernstige symptomen van de ziekte verminderen na gebruik.

Additional remarks
In Nederland zijn geschat 3.000 patiënten met myasthenia gravis (167 per miljoen) , de helft hiervan gebruikt immunosuppressiva (rond de1.500) en bij 10 tot 20% hiervan wordt wegens problemen met chronische stabiliteit derdelijns medicatie overwogen waaronder complementremmers (150 tot 300) (1). Hierbij zullen slechts enkele kinderen zijn. Het zou om totaal 30 kinderen in Nederland gaan en als daarvan 10% complementremmers nodig heeft gaat het om hooguit 3 patiënten (2).
